Title: Frost sensor
Inventor: GOTOU NORIO
IPC: G01H11/04
Filed: 1980-06-25
Abstract: PURPOSE: To obtain a high-sensitivity frost sensor which is free from a malfunction and has an increased dynamic range for detection of frost, by installing an elastic wave exciting coil and a detection coil at the support part of a magnetic distortion ribbon.  
     CONSTITUTION: An input coil 3 and an output coil 4 are provided at the adhesion parts across an amorphous magnetic distortion ribbon 2 to a supporter 1, and at the same time a bias magnet 5 is adhered to the lower part of the supporter 1. When the current flowed to the coil 3, a distortion is produced to the ribbon 2. Then the elastic wave propagates to the coil 4 to be detected in the form of an electric signal. If the ribbon 2 is frosted, a propagation loss is caused to the elastic wave to be detected as reduction of reproduced voltage. In such way, a high-sensitivity frost sensor is obtained with an increased dynamic range for detection of frost and with no malfunction.

When the time comes, a synchronization control part 140 outputs a restart signal to the reference code generation part and lets the reference code series newly generated from the leading bit. Thus, the reception code series and the reference code series are forcedly synchronized.

Title: Solenoid valve
Inventor: KATO YASUO
IPC: F16K31/06
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent generation of shock noises accompanied with closing operation of a solenoid valve. SOLUTION: A solenoid valve 1 has a first spring 13 which energizes a valve body 12 in an opening direction, and a second spring 14 which energizes the valve body 12 in a closing direction. The valve body 12 is suspended at the position where balancing is generated between energizing force of the first and second springs 13, 14 under the state of setting OFF an electromagnetic device. The second spring 14 has unequal pitches and non-linear load characteristics. It is thus possible to increase inclination of synthetic load characteristics of the first and second springs 13, 14, finally at its overshooting side of the valve stopping position, compared to the valve closing side of the valve stopping position.  It is therefore possible to set a second moving stroke that the valve body 12 passes the stopping position smaller than that the valve body 12 moves to a position for closing a valve port 16 from the stopping position.
